If you can get the potatoes soft.....this is for 4 - 5 russet potatoes - just add enough butter to choke a camel 1/2 to 3/4 of a cup, milk for creaminess (add a little at a time), and salt to taste. And not just a little salt, like a teaspoon. Mmmmm! If I just mention mashed taters my daughter will want me to cook them!

I'm SURE if you cube the potatoes and put the crockpot on high, they will eventually cook enough to mash. Maybe 1 or 2 or so hours I'm guessing?
